Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1077LZ-66 is determined by strict alignment across the following critical parameters:

• Frequency range: 8.13kHz ~ 66.7MHz
• Supply voltage: 2.7V ~ 3.6V
• Supply current: 30 mA
• Operating temperature: -40°C ~ 85°C
• Package type: 8-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• Functional type: Oscillator, Fixed Frequency (Dual)

Only components matching all specified electrical and mechanical parameters qualify as direct substitutes. The DS1077LZ-66+ meets these criteria and is classified as a direct manufacturer equivalent.

Parameter Comparison

Engineering Selection Recommendations

The DS1077LZ-66+ serves as the direct functional equivalent to the DS1077LZ-66. Both components share identical electrical specifications and package geometry, ensuring pin-for-pin compatibility and functional interchangeability in circuit applications.

A key distinction exists in regulatory compliance: the DS1077LZ-66+ achieves ROHS3 compliance, whereas the original DS1077LZ-66 is RoHS non-compliant. For applications subject to RoHS directives or environmental regulations, the DS1077LZ-66+ is the appropriate selection. Both parts maintain identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Frequently Asked Questions (FAQ)

Q: Can DS1077LZ-66+ be used as a direct replacement for DS1077LZ-66?

A: Yes. The DS1077LZ-66+ is electrically and mechanically identical to the DS1077LZ-66. Both components operate at identical frequency ranges, supply voltages, currents, and temperature specifications. The 8-SOIC package geometry is identical, enabling direct PCB substitution without layout modifications.

Q: What is the difference between DS1077LZ-66 and DS1077LZ-66+?

A: The primary difference is RoHS compliance status. The DS1077LZ-66+ is ROHS3 compliant, while the DS1077LZ-66 is RoHS non-compliant. All electrical and mechanical parameters remain identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 8-SOIC (0.154", 3.90mm Width) package with identical pinout and mounting requirements. Surface-mount assembly processes remain unchanged.

Q: Why is the DS1077LZ-66 marked as obsolete?

A: The product status reflects manufacturer discontinuation. The DS1077LZ-66+ remains available as the current equivalent offering from the same manufacturer.

Q: What supply voltage range does this oscillator support?

A: The DS1077LZ-66 and DS1077LZ-66+ both operate across a 2.7V to 3.6V supply voltage range with a maximum supply current of 30 mA.

Q: What is the operating temperature range?

A: Both components operate across -40°C to 85°C, suitable for industrial and commercial temperature environments.
